We need to finish writing out the problem using what we know about the distance both planes traveled.

Plane 1 - 1050 miles - 300 mph - ? time

Plane 2 - 1050 miles - same time as Plane 1 less 1.75 hours.

Let's fill in the gaps.

Plane 1 - ? time 1050/300 = 3.5 hours

Plane 2 - ? time Take 3.5 hours and subtract 1.75 = 1.75 hours

Now we figure the speed of plane 2

1050/1.75 = 600 miles an hour

Another quick way was to note that 1.75 was half of 3.5 hours so the speed was 2x as fast!

max2010maxim [7]
Luis earns a solid $150 and that doesn't change, now you need to calculate 14% of $6,050. 
x=150+(0.14x6050)
    150+(847)
    997
Luis was paid $997.

A function has a slope of 3, and one solution is given in the table. identify the missing outputs. x: 5 6 7 8 9 y: -50
svetlana [45]

The remaining value will increase by the value of the slope. Hence the remaining missing values are -47, -44, -41, -38 and -35

<h3>Slope and tables</h3>

The slope of a line is the ratio of the rise to run of a line. It is also defined as the rate of change of coordinate y with respect to x. Mathematically;

slope = change in y/change in x

If the slope of the table given is 3, then using the coordinate points (5, -50)and (6, y)

Substitute

3 = y-(-50)/6-5
3 = y+50/1
y+50 = 3

y = -47

The remaining value will increase by the value of the slope. Hence the remaining missing values are -44, -41, -38 and -35

What is the quotient??
Mars2501 [29]

The answer is A) 2x + 7.

When you are doing synthetic division, you always pull down the first number to the end area like this.

1 ║ 2 9 7

2

After that you multiply it's result by the number in the front. Then you add it's result to the second number. 2 * -1 = -2. So we add -2 to 9 and pull that down.

1 ║ 2 9 7

2 7

Now we repeat that process and multiply the 7 by -1. The result is -7, and we add that to 7.

1 ║ 2 9 7

2 7 0

If the end result is 0, that means the division went in evenly, with no remainders. We can now add an decreasing number of x's to all of the numbers that came through other than 0.

2x + 7
